ATTACHMENT FOR CYLINDERS IN THRESHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent 1T0. 671,325, dated April2, 1901.

Application filed May 4, 1900.

To all whom, it may concern.-

Be it known that 1, JOHN RINGK, of the city of Belleville, St. Claircounty, State of Illinois, have invented certain new and usefulImprovements in Attachments for Cylinders in Threshing-Machines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof.

This invention relates to attachments for cylinders inthreshing-machines; and it consists of the novel construction,combination, and arrangement of parts hereinafter shown, described, andclaimed;

Figure l is a view in perspective of a part of a cylinder, showing myimproved attachment secured thereto. Fig. 2 is an enlarged plan view ofa portion of the cylinder. Fig. 3 is a sectional view taken on the linea ct of Fig. 2. Fig. 4 is an end elevation of one of the attachmentstandshows the means which I employ to secure the same upon the cylinder.Fig. 5 is a detail view of the under side of the attachment.

This invention consists of integral castings comprising the arcuate ribs1, cast in corrugated form, and the longitudinal strips 2, the saidstrips being adapted to project into the cylinder,while the corrugatedribs extend beyond the surface. The castings arearranged in pairs, thearrangement of which is best shown in Fig. 5, and one look has beenfound sufficient to hold both securely in position on the cylinder. Thecasting 3 in the drawings is provided atone end with an integral portion4 inwardly from the end rib,andin the outer surface of said portion is adepression 5,which is of a depth suficient to receive the heads ofscrews, bolts, or other fastening devices which may be made use of.Through the said portion are arranged a pair of apertures, through whichextend screws or bolts 6, and to the inner end of one of said screws ispivotally secured a lock-strip 7, the end of the screw being bradded orflattened for the purpose of more securely holding the lock-strip inposition thereon. The screw at the other end is threaded into anaperture in the said strip and may be removed therefrom, in 50 whichcase the strip may be turned, the remaining screw acting as a pivot.When the Serial No. 15,469. (No model.)

lock-strip is adjusted in position, its ends project a suitable distancebeyond the sides of the strips 2 and engage under the horizontal strips8, rigidly carried by the cylinder. Heretofore threshing-machines havefor the most part been constructed with smooth cylinders or cylindersapproximately smooth, and by means of these cylinders it is practicallyimpossible to obtain satisfactory results in threshing heavy grain,owing to the fact that by use of such cylinders all the grain cannot beshelled from the head, thereby resulting in much loss and waste.

' My invention has for one object to provide 6; a suitable attachment ora series of attachments to be applied to threshing-machine cylinders ofordinary construction, and by means of which all the grain can beremoved from the head. These attachments consist, es- 7o sentially, of aseries of projecting ribs to be secured upon the periphery or thecylinder and to project outwardly therefrom, and which operate withinthe depressions usually provided in the concave. By this means the headsof the grain are scratched and rubbed between the concave and theprojecting ribs, and all the grain is thereby freed from the heads,allowing it to be separated from the straw and chaff and resulting inmuch more grain being saved than can be done by use of the ordinarysmooth cylinder. These ribs are formed in separate castings, so thatwhen one becomes injured it may be removed and another substituted.

Further objects and advantages will appear in the following description,and the particular features of construction of the invention arehereinafter fully set forth.

The device is constructed for use on cylin- 9o ders of any ordinaryconstruction,and to avoid the necessity of using more than one look Iextend the strips 2 integral with the casting 3 a suitable distancebeyond the arcuate rib at the end opposite from the lock above de- 5scribed. The projecting ends are joined by an integral member 9 and whenin use on the cylinder fit under the cylinder-band 9 which effectuallyprevents displacement. The arcuate rib at the other end of the castingprojects beyond the strips 2 a sufficient distance to receive theprojecting ends of the strips 2 integral with the casting 3, while thestrips, at the opposite end of the said castingarelli:

lating the lock hereinhefore described and another can be substituted inits place.

By referring to Fig. at it appears that the end of each ribabuttingagainst the cylinderteeth is cut on a slant, the purpose of which is toallow the teeth to fall out in case they become broken without injury tothe ribs.

I claim 1. The herein-described attachment for threshing machinecylinders, comprising a casting having integral arcuate ribs, connectingand supporting bars integral with said ribs, and means for locking saidattachment on a suitable skeleton cylinder vcomprising end heads andbands and the longitudinal threshing and toothed bars which theattachment is adapted to engage, externally by the said connecting andsupporting bars carrying the arcuate ribs and internally by the saidlocking device, substantially as specified.

2. A device of the class described, comprising a casting havingcorrugated arcuate ribs, a skeleton frame integral with said ribs and amovable lock for retaining the device in position, the said device beingadapted to be attached to a skeleton cylinder comprising Should any onebecome injured or. useless, it can be easily removed by manipu end headsand bands and the longitudinal threshing or toothed bars-whiohitheattachment is adapted to engage by means of the said skeleton frame andthe said movable lock, substantially as specified.

3. The herein-described attachment for threshingmachines,- comprising apair of castings having arcuate corrugated ribs, connecting andsupporting bars integral with said ribs, a lock carried by one of saidcastings for holding it on the cylinder, means whereby the castingcarrying the lock engages the other casting, the said castings havingprojections to engage with the bands of the cylinder to which they areadapted to be attached, the castings being adapted to engage thelongitudinal threshing-bars of the cylinder, externally by the saidconnecting and supporting bars and internally by the said lock,substantially as specified.

4. As an article of manufacture, an attachment for threshing-machinecylinders comprising a pair of castings having arcuate corrugated ribs,connecting and supporting bars integral withsaid ribs, a lock carried byone of said castings, and means whereby the casting carrying the lockengages the other casting, the said castings being adapted to beattached to a skeleton cylinder comprising end heads and bands andlongitudinal threshing or toothed bars, which. the attachment is adaptedtoengage, externally by the casting or supporting-bars carrying thearcuate ribs and internally by the said locking device, substantially asspecified.-

In testimony whereof I aflix my signature in presence of two witnesses.
